Cladonia rangiferina, or reindeer moss, hanging on trees in the Forest at Otsamo, Lapland. The slow growing lichen provides an important part of reindeer diet during the cold winter months. A campaign by Greenpeace activists and Sami reindeer herders to protect old growth boreal forests near Inari, Lapland, in Northern, Finland, led to 80,000 hectares of forest being saved from logging. After a six year battle, the forests continue to be used by the Sami people for reindeer herding.
